the Leg mode, unless the mode change was made on the “from”
side in which case the KLN 89(B) will calculate the correct
desired track for the new leg.
3. With the exception of #2 above, the characteristics of normal
Direct To operation apply.
4. If the active waypoint was part of the active flight plan (FPL 0),
the system will revert to normal flight plan operation once the
active waypoint is reached.
4.7.6. GOING DIRECT TO A WAYPOINT WHILE IN THE OBS
MODE
The direct-to function will select the OBS value that will take the air-
craft from the present position direct to the active waypoint when the
KLN 89(B) is not the displayed navigation source on the external indi-
cator.
If the KLN 89(B) is the displayed navigation source on an HSI or CDI
it is not possible for the KLN 89(B) to
change the OBS value. In these situ-
ations the KLN 89(B) will provide a
scratchpad message that will tell you
what OBS value should be selected
to go direct to the active waypoint
(figure 4-123).
4.7.7. ACTIVATING A WAYPOINT WHILE IN THE OBS MODE
While in the OBS mode, you may activate another waypoint by using
the normal Direct To method or by using a second method. This sec-
ond method activates another waypoint without changing the
selected course (OBS). In other words, when the new waypoint is
activated, the D-Bar is not necessarily
recentered. In figure 4-124 the KLN
89(B) is in the OBS mode and the
selected course is 149°. You have
just crossed ARG and desire to
activate the next waypoint in the flight
plan, GQE, without recentering the D-
Bar.
